How the loan calculator works
- Enter the amount borrowed, annual interest rate, and repayment term.
- The calculator applies the standard fixed-payment amortization formula, including support for zero-interest loans.
- Review the estimated monthly payment, borrowing cost, and payment-by-payment balance.
This estimate assumes a fixed interest rate and equal monthly payments. It does not include fees, taxes, insurance, or lender-specific rounding.
